cast in a slotted mold it is customary to eject the slug edgewise fromthe mold between two lmives,which insure the parallelism of the o positefaces and the roper thicknessof t e slug, these knives eing adjustablein order that the slugs'may be trimmed toone' thickness oranother, asdemanded.-

My invention relates to improved means for supporting and adjusting one'of the knives, the object being to secure instantaneous and veryaccurate adjustment and the firm support of the knife in the exactposition re uired. To this end I mount the movable ife on a slidetapered in crosssection and combined with adjusting and binding screwsin such manner that it may be quickly and accurately adjusted todifierent predetermined positions and then looked firmly in place.

Referring to the drawings, Figure 1 represents a perspecti've view ofthe mold-wheel of a Mergenthaler linotype-machine with myknife-supporting mechanism in operative relation thereto. Fig, 2 is aperspective view looking against the inner orrec-eivin faces of theknives with the adjustingan' supporting devices. Fig. 3 is a horizontalcross-section on the line 3' 3 of Figs. 3 and 4.

Fig. 4 is a vertical cross-section on the line 4 4 of Figs. 2 and 3.Fig; 5 is a face view of the knife-supporting slide. J

Referring to the drawings, A A represent stationary portions of themachine-frame; B O, the two upright arallel knives between which theslugs or otypes are delivered edgewise as they leave the mold by theusual ejector-blade.

The knife B is secured rigidly to the frame by clamping-bolts b or inany other suitable manner.

horizontal supporting-slide D of the form It will be observedthat thisThe opposing movable knife 0 is; secured firmly by bolts 0 orotherwiseto a" upright portion, to which the knife is secured,

and having a horizontal portion of tapered form in cross-section, asshown in Fig. 4. This. taperedportion isseated in a correiponding groovein the frame A, as shown in ig. 4, and isheld in place therein bya clamping-screw E, passing throu h a horizontal slot in the frame, its inneron I being threaded into the slide D, while its outer end is providedwith a handle 6, secured 'firmly thereto.

By means of the handle, the screwmay be turned so as to force the slidefirmly into its the knife 0 very rigidly in position, or the screw ma beturned in the o posite direction to re ease the slide and ad mit of itsbeing moved endwise horizontally to change the distance between the twoknives. The tapered form of the slide in cross-section is important inthat it permits the slide to be clamped very securely in the exactposition be in no danger of displacement by the severe pressure to whichit is subjectedby the outgoing slugs. 'Ihe tapered form also admits ofcompensation for wear of the sliding parts, so that there is no dangerof the slide being loosely or inaccurately guided.

For the purpose of efieeting the movement of the slide and knife Iprovide the screw F and one or more springs G. These s rings extendloosely through a rib on the sli e and bear at one end against the knifeO and at the opposite end against the main frame, their tendency beingto advance the knife 0 toward- .its com anion, and thus reduce the spacebetween t em.

The screw F has its inner end pinned-fast to a rib on the slide '1) andits outer and threaded end extended through an upright nut H in the formof a handwheel, the hub of which bears against the outer side of I theframe A. When this wheel is turned inone direction, it acts through thescrew F to move Patented Nov. 27, I906.

' tapered seat, thereby confining the slide and lre fiuired, so that theknife carried thereby the slide D and knife 0 outward, and when turnedin the opposite direction it allows the screw to move in the reversedirection and permits the knife 0 to be moved inward by.

the springs G toward the knife B.

The periphery or the wheel, which is without lateral movement, isprovided with] a spifal line'and with adjacent gradnations or marks atdifferent points in the length; of the line, to be read in connectionwith a pointer cated that in order to set the knife for trimming slugsto standard thicknessessuch"as minion, long-primer, & c.it is onlynecessary to turn the wheel until the proper graduation is broughtopposite the pointer. As the pointer I' is moved laterally by the slide,while the wheel or nut H is without lateral motion, the pointeris'adapted to follow a spiral line on the periphery of the wheel, asindicated in Fig. 2. This permits the use of. graduations extendingintwo or more lines around the wheel, so that the wide range ofadjustment maybe provided. Prior to this adjustment the screw E isturned to release the slide, and after the adjustment is effected thescrew is again turned to bind the slid firmly in place,

In order tofacilitatetheproper adjustment or location of the knife 0upon the slide D whenit is being secured thereon and to give it sup ortagainst the pressure of the slug, I provi e two screws J, passinghorizontally through the rib on the slide and bearing against the outeror back edge of the knife, as shown in Figs. 2 and 5.

The essence of my invention consists in combining with the movable knifea supporting-slide accurately guided in the frame, with means for movingthis slide to predetermined positions and means for confining itsecurely in the desiredposition, and it is manifest that the details maybe variously modified without changing essentially the mode of action orpassing beyond the scope of my invention.

For the purpose of supporting and guiding the slug after it has passedthe knives I provide the usual hinged plate K, acted upon by a spring Lbut thesefeatures,,although shown, formtno part of the presentinvention.

The part of the frame which carries the slide D and wheel may be made inany suitable form and bolted or otherwise removably attached to themachine-frame, so as to constitute a unitary knife-adjusting structure,which may be applied to or removed from the machine at will. Inthedrawings the line of separation between this part and themain frame isindicated at M.

.It is to be observed that my knife-sustaining slide D is combined withmeans for moving'the same and the knife thereon to definite orpredetermined positions and with independent means for clam-ping itfirmly in each position. I am thus enabled to control the knife in suchmanner that the'slu s may be trimmed to the exact standard t' icknessesI required and with their opposite faces exactly parallel.

Having described my invention, what I- ,claim is 1. In a slug-trimmingmechanism for 1ino-' type-machines, the combination of the movab eknife, its supporting-slide guided in the frame, means for adjusting'theslide to predetermined p ositions and independent means for clamping theslide in the required positions;

In a linotype-machine, in combination with a fixed supportingmember, a slide guided therein, a slug-trimming knife secured rigidly tothe slide, a spring tending to move the slide in one direction, a screwmechanism for-moving the same in the o posite direction, and means forclamping an slide at will. 3. In combination-with a supporting-frame A,the slide D guided-therein, the knifefixed to the slide, a springtending to move the slide in one direction, the screw and hand.- wheelfor -movin the slide inthe opposite direction, and in ependent meansacting to clamp the Slide in ts different positions.
